ADAM KLEMM, OF ST. LOUIS, MISSOURI.

SAND-WASH ER.

To all whom it may concern.-

Be it known that I, ADAM KLEMM, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented new and useful Improvements in Sand-W'ashers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide improved means for washing sand and removing impurities therefrom.

My invention consists in the construction, arrangement and combination of parts, hereinafter set forth, pointed out in my claim, and illustrated by the accompanying drawings, in which- Figure 1 is a sectional elevation of the apparatus on the line 11 of Fig. 3. Fig. 2 isa sectional elevation of the apparatus on the line 2-2 of Fig. 3. Fig. 3 is a plan View of the apparatus. Fig. 4is ahorizontal sectional View on the line 44 of Fig. 1.

In the construction of the apparatus as shown, the numeral designates a receptaole, preferably made of sheet metal, and provided with a bifurcated lower portion'forming hopper bottoms 11, 11. The receptacle 10 is oblong in plan View, and has, located in the upper portion thereof, two inverted kettles 12, 13. The kettles 12, 13, have rounded and arched bottoms 14, and are secured to the receptacle 10 by means of hooks rigidly connected to the sides of the kettles and engaging the upper edges of the sides of said receptacle. Pipes 16 and 17 are provided, one end of each pipe communicating with areservoir (not shown), the remaining ends of said pipes leading through the side of the receptacle immediately above the hopper bottoms 11, and communicating with the interior thereof in vertical alignment with the centers of the kettles 12, 13.

A waste pipe 18 is provided, which communicates at one end with the upper portion of the receptacle 10, and leads therefrom to a point of discharge (not shown).

Discharge ports 19 are provided in theapices of the hopper bottoms 11, 11, and, located immediately below said discharge ports is a receptacle 20 of similar shape to, and greater transverse dimension than, the receptacle 10.

Patent No. 535,011, dated March 5, 1895.

Serial No. 513,452. (No model.)

The receptacle 20 has abifurcated lower portion forming hopper bottoms 21, 22, which bottoms have at their apices ingress ports 23, 24, through which feed pipes 25,26, communicate with the said receptacle. The opposite ends of the feed pipes 25, 26, communicate with the water reservoir (not shown). Inverted kettles 27, 28, having arched bottoms 29, 30, are located in the lower portion of the receptacle 20, in

vertical alignment with the ingress ports 23, 24, and are secured to the sides of said receptacle by meansofbrackets3l rigidly connected thereto.

Transversely and horizontally positioned in the lower portions of the kettles 27, 28, are sand discharge pipes 32, which pipes lead to the exterior of the receptacle and have reduced end portions 33, with reduced bores, at their outer ends. is cut away at 34, within the kettles 27, 28, thereby forming slots in the upper sides of said pipes, the inner ends of said pipes being closed.

Transversely and horizontally positioned in the upper portion of each of the kettles 27, 28, at right angles to the pipes 32, are pipes 35, which pipes lead to the exterior of the receptacle 20 and have reduced end portions 36, with reduced bores, at their outer ends. The inner ends of the pipes 35 are closed, and a portion is cut away from each pipe at 37, thereby forming slots in the upper sides of said pipes within the kettles 27, 28. Located immediately above and in alignment with the arched bottoms 29, 30, of the kettles 27, 28, are deflecting plates 38, 39, which plates are secured to the receptacle 20 by means of brackets 40.

Sand conveying pipes 4:1, 42, lead from initial points within the centers of the kettles 12,13, downward out of said kettles, laterally through the side of the receptacle 10, downwardly along the receptacles 10 and 20,1aterally into the receptacle 20 and to points of downward discharge immediately above and in alignment with the deflecting plates 38, 39.

Communicating waste pipes 43, 43, are located in the upper portion of the receptacle 20, which pipes have a common ingress port 44, and discharge outside the said receptacle.

Each of the pipes 16, 17, 25, and 26, are provided with stop-cocks 15 by means of which A portion of each pipe 32 the flow of water through the said pipes may be controlled and cut oil.

The operation of the apparatus is as followsz-The sand to be cleansed is thrown, or otherwise deposited, on the arched bottoms of the kettles 12, 13, and is deflected thereby and scattered throughout the receptacle 10. Water is introduced through the pipes 16, and 17, the force of the water carrying the light sand into and through the pipes 41, and 42. Thelight sand only which passes through the pipes 41, and 42, is to be saved. It is deflected by the plates 38, 39, upon the arched bottoms 29, 30, and scattered by the said bottoms in such a manner as to receive the full force and effect of water forcibly introduced through the pipes 25, 26, whereby the sand is thoroughly Washed, the lighter portion comprising the dirt and other impurities from the sand are carried away through the pipes 43, 43 and the cleansed sand driven through the pipes 32, 32 and 35, 35 the heavier particles passing out through the pipes 32, 32.

What I claim is- A sand washer comprising an initial receptacle having a pair of hopper bottoms, a series of inverted kettles suspended in the upper portion of said receptacle upon which the dry sand is manually thrown, a series of water supply pipes communicating with the said receptacle in the axial planes of said kettles, a waste pipe 18 leading from the top of said receptacle, drain vents 19, 19, in the hopper bottoms, a washing receptacle of greater transverse dimensions, located beneath the initial receptacle and in vertical alignment therewith, a series of inverted kettles 27, 28, mounted in the lower portion of the washing receptacle, a series of water supply pipes 25, 26, communicating with the washing receptacle below, and in the axial plane of the kettles 27, 28, sand discharge pipes adapted to con vey the heavy sand from the kettles 27, 28 to the exterior, sand conveying pipes 35, 35, located above the pipes 32, 32, and adapted to convey the lighter sand to the exterior, defiecting plates 38, 39, located above the kettles 27, 28, pipes 41, 42, adapted to convey the combined sand and water from the kettles 12, 13, to and upon the deflecting plates 38, 39, and a waste pipe 43 leading from the upper portion of the Washing receptacle 20, as shown and described.

In testimony whereof I have affixed my signature in presence of two witnesses.

ADAM KLEMM.
